# Flow Link vs One Line

The clearest difference is ads: One Line at none against Flow Link's shown. Flow Link's advantage is update cadence (every 2 weeks vs every 2 months) and iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Flow Link sells 9 in-app purchases, starting at $3.99 per month and One Line sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Flow Link ships an update every 2 weeks, One Line every 2 months. Both last shipped on October 31, 2026.
